Whats the score with this migration code or am i the only person that have not used this?

I changed provider 3 times now (adsl) and never requested a MAC code, but i am always hearing that people have to request this? Why? and whats so special about it?

As far as i know it it a code you give to yout new provider to say that your current isp has given you the all clear etc and everything is hunky dory . I personally think its twoddle and you should be able to switch providers like you do with your mobile phone.Unlock the phone and put a new sim in ?

If you don't use a MAC then the effect is of a 'cease' and 'provide', and can take days if your are not lucky.

Getting a MAC from the losing provider and handing it to the gaining should ensure a downtime of minutes.

Note that the MAC system is relatively recent - when ASDSL first started it wasn't part of the system.

The purpose of the MAC system is to counteract 'slamming'. This is where an unscrupulous provider could transfer a whole lot of accounts from other providers to itself without the owners being aware, or agreeing.

Migration Authorisation Code - pretty much what Harry says. Don't think it's quite as bad now, but some ISPs (such as the one I used to work for) could be downright arsey about providing it to you. However, you should note that it is illegal for them not to provide a MAC if you request one.
